If 80% is 72 marks what is full marks

can someone tell me the answer please

Answers

Answer 1

Answer:

80% = 0.8

100% = 1

0.8 = 72

1 = x

0.8* x = 72 * 1

x = 72 / 0.8 = 90

0.8 * 90 = 72

80% * 90 = 72

Provide an example of a real-world relationship where there is no clear independent or dependent variable.

Answers

Answer:

Price and Demand

Step-by-step explanation:

We need to find a real-world relation in which the independent and dependent variables are not clear.

Let us consider, the price and demand relationship of a product.

In this relation, sometimes the demand of the product depends on its price and sometimes the price of the product varies according to its demand.

Thus, the independent and dependent variables changes according.

So, there is no clarity of the independent and dependent variables in the relation between the price and demand of a product.

If you consider humans, a single human is not capable of doing everything.

In Some ways he is dependent on other humans for different purposes.

But you can say that he or she is Independent , he or she has got his or her unique identity by saying he has got different features like body structure, appearance, Face, eyes etc... . He or She is different from others. So this way he is Independent,

But by considering man as Social animal , you can say that we humans are not independent but dependent on each other for survival or for our existence on this planet called earth.

→→A Single Human ⇒ Humans( there is no clear independent or dependent variable)

One angle in a triangle measures 120°. Which of the following could not be one of the other angle measures?20°

33°

45°

73°

Answers

73 BECAUSE there are 180 degrees in a triangle when all the angles are added together. If one angle is 120 then the other angles must add up to 60 (180-120=60). It can't be 73 because then that means there would be no other angle and there has to be 3 angles in a triangle.

That would be 73 degrees.

A: Miguel says that you can easily separate numbers divisible by 2 into two equal parts. Do you agree? Why or why not?B: Manny says that if Miguel is correct, then you can easily separate numbers divisible by 3 into three equal parts. Do you agree? Why or why not?

C: Lupe says that if any number is divisible by n, you can easily separate it into n equals parts. Do you agree with her? Explain.

Answers

Answer:

Step-by-step explanation:

A. Yes,Miguel is correct because all even numbers are the multiple of 2 and when we divide any even number resultant will be a whole number which represents the number of equal parts.

Example: 8 ÷ 2 = 4

B. Yes, Because all numbers which are multiple of 3, when divided by 3 resultant will be a whole number which represents the equal number of parts.

Example : 6 ÷ 3 = 2

C. Yes, Lupe is correct. When any number multiple of n is divided by n we get a whole number which represents the number of parts divided equally.

Example : 2n ÷ n = 2

A. Yes, the number 8 is divisible by 4. You can split it into two, 4 and 4.
B. Yes, the number 99 is divisible by 3, You can split it into three equal parts.
33,33, and 33.
C. Yes because it works like that for all of the numbers.
Hope this helps.
